Tertiary recycling of waste polystyrene using magnesium impregnated catalysts into valuable products

White cement and burnt brick powder catalyzed pyrolysis of waste polystyrene for production of liquid and gaseous fuels

“…3,5 The amount and nature of these compounds may vary according to the nature of catalyst and reaction conditions of the pyrolysis. The oil quantity varied slightly with type of the catalyst and catalytic and noncatalytic processes.…”

“…Based on literature on pyrolysis of waste polystyrene, it is believed that maximum liquid amount can be achieved through catalytic pyrolysis without the formation of solid residue. 3,5 The amount and nature of these compounds may vary according to the nature of catalyst and reaction conditions of the pyrolysis.…”

“…The wasted plastic is one of the nonbiodegradable wastes. [3][4][5] Both the thermal and thermo-catalytic pyrolysis of polystyrene are the chain scission reactions. Waste polystyrene is included in the most abundant plastic wastes.…”

“…1,2 Some researchers used metal impregnated catalysts for increasing the yield of styrene from the pyrolysis of waste polystyrene. [3][4][5] Both the thermal and thermo-catalytic pyrolysis of polystyrene are the chain scission reactions. However, the thermal cracking may be random, and the catalytic cracking may have selectivity.…”

Utilizing Waste Thermocol Sheets and Rusted Iron Wires to Fabricate Carbon–Fe3O4 Nanocomposite‐Based Supercapacitors: Turning Wastes into Value‐Added Materials

“…[26] To meet essential criteria to recycle or degrade thermocol sheets, variouse fforts have been explored and some are in progress. The resulting carbon, Fe 3 O 4 nanoparticles,a nd CÀFe 3 O 4 composites are used as electrode materials for supercapacitor applications.…”
